What does millimeter water (4°C) measure?

It measures the hydrostatic pressure exerted by a 1 mm column of pure water at 4 degrees Celsius, commonly used for very small pressure measurements.

Where is the exapascal unit typically used?

Exapascal is used to express extraordinarily large pressures in astrophysics, high-energy physics, and theoretical studies involving extreme pressure scales.

Why are the converted values so small?

Because the exapascal represents an extremely large pressure scale, converting very small pressures like millimeter water (4°C) results in values close to zero on that scale.
